Continuous Read and Analyze Microphone Data

Recommended for High School through College.

Introduction

In this exercise, you will create a simple program using the Analog Express VI and the Spectral Measurements Express VI to continuously collect microphone data and continuously perform an FFT analysis on the data. A Fast Fourier Transform (FFT) is a mathematical algorithm commonly used in digital signal processing to determine the dominant frequencies in a complex waveform.

Objectives

In this experiment, you will

Create a LabVIEW VI to continuously collect and analyze data.

Incorporate LabVIEW Express Analysis functions.

Use a While Loop to keep collecting and analyzing data until stopped by the user.
